Step 20: Draw a series of curved, triangular shapes along the water dragon's back for spikes. Make the spikes bigger at the top and smaller along the sides. Dragons are fictional, so feel free to draw your spikes as big or as small as you'd like. Make the spikes thinner and smaller as you draw them farther down along the tail. Near the bottom, draw the spikes across the shape of the tail so that they end up on the other edge. Continue to draw the spikes along the top edge of the dragon's tail.
Step 21: Use the initial lines and shapes as guides to draw the rest of the water dragon's body. Add a few extra lines under the head to emphasize the twist of the neck. Darken the outer edges of the initial guides to create the shape of the dragon's body. As you darken the lines, don't overlap the appendages that are on this side of the body.
Step 22: At the tip of the tail, draw a long, curved, spike-like shape for the top part of the tail's fin. The shape is basically made up of two curved lines that come to a point at the top. Add a smaller fin at the bottom so that the is similar to a crescent moon. Draw a series of long, curved lines along the underside of the water dragon's body for the edge of the bottom scales. Follow the curvature of the body as you draw these lines. Don't overlap the appendages.
Step 23: Draw a series of short, curved lines along the underside of the water dragon's body for the armored scales. The lines under the head should be horizontal, then gradually turn vertical under the body. Draw a series of different-sized circles around the body for the underwater bubbles. Keep the bubbles clustered together in small groups. Draw as many as you'd like!
Step 24: Go over the final sketch lines with a pen, marker or any other type of permanent ink. Take your time and be careful when you ink to avoid any accidents. After the ink dries, get rid of every pencil mark with an eraser for a cleaner drawing.
Final Step: Dragons are fictional, so color your drawing however you want! For this look, use blue-green for the main part of the body to imitate the color of water. For now, leave the underside of the body, including the jaw, blank. Use light blue-green or just plain light blue for the underside of the water dragon's body and the webbing.
Color the horns, the spikes on the back and the tail fin dark blue-green. Use dark red for the inside of the dragon's mouth and pink for the tongue. Add a bit of light blue to the bubbles. Use a bit of dark blue-green throughout the body as shadows to give the figure more dimension and volume. Don't forget to pause the video after each step to draw at your own pace. If you'd like, you can add some spots on the back using dark blue-green.
